To all yghorn it' rnay concern:

RELL and ARCHIBALD'MERRELL,0itiZeIlS of the United States, residing atSoda S rings, in the county of Bannock and State of idaho, have inventedcertain new and useful Improvements' in .fioldering Compounds, of

which the following is, a specification.

This invention relates to improvements in soldering compounds.

-' Theo ject of the invention is to provide a soldering compound or fluxwhich will be of wide application to various metals for solder-- ingpurposes such as iron, zinc, copper, brass,

tin and nickel, and other known metals, and

compositions thereof.

Further, the invention .aimsto provide a 7 compound or flux which willavoid the necessity of removing grease or other fatty collections ofmatter from the object to be sol dered. I

According to the invention as now practiced we employ the followingingredients measured by weight in the-proportions below indicatedIngredients. Parts.

Sal ammoniac....;- 11 Powdered rosin 8 Powdered borax 1 Bi-carbonate ofsoda. g Blue vitriol a brush, cloth. or other instrument, after 1 whichthe solder in its melted or semi+fluid Patented Sept. 29, 1908.

v I state is ap' lied, as is we'll known to those Belt known that we,EDMONDM. MEIF 1i 7 it "may be used andis applied to, third,- it

- may used on more known metals and compositions thereof than ispossible with usual fluxes, and finally it will tin a soldering iron aninappreciable period of time, thirty seconds having been ascertained byexperiment as the actual time required.

The use of blue vitriol has been found to accentuate the properties ofthe compound and increase the efficiency in the respects herein noted.

Having thus described our invention, what we claim is:

1. A soldering compound composed of sal ammoniac, powdered rosin,powdered borax, bi-carbonate of soda and blue vitriol.

2. A soldering compound composed of eleven parts of sal ammoniac, threeparts of powdered'rosimone part of powdered borax,

one-half. part of blue vitriol. Y

3. A soldering compound composed of sal ammoniac, powdered rosin,powdered borax, bi-carbonate of soda and blue vitriol thor 'oughlymixed, and mixed in the proportion of one part ofsaid compound in threeparts of water.

In testimony hereof we aflix our signatures, in presence" of twowitnesses.
